I am about to solder up my first few packs, and I have already decided I want to build 14S8P packs and have them completely wired into a common BMS/balancer. So there'll be 15 wires connecting each pack to the system. For all the arguments for and against this method, the one that tipped the balance for me is the ability to grab a pack or 2 and use them for a portable power source. It also has a few other advantages, but the purpose of my post is not to justify the paradigm, but rather to ask a simple question.
I am all set to build packs of 14S, but yesterday I read a thread regarding the benefits of 15S. The need to only charge up to 3.92V per cell to get 58.8V, and then discharging to 3.2 (48V) must surely be a significant boost to cycle life. It also means that in a pinch, I could run the packs down a bit more if I had to.
So what are people's thoughts on 15S over 14S?
